为基于 Java 文本的游戏制作控制台

Making A Console For A Java Text Based Game

提问by joejoethemonkey

So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD). I do not know how to do this as of yet, because I am quite new at coding, can anyone help me? And it could be like a simple console because im not looking for a complex GUI or anything at the moment.

所以，我一直在尝试用 Java 制作一个简单的基于文本的 RPG，而且进展顺利，我的朋友也想玩它，但他们不太懂技术，所以很难告诉他们得到一个IDE 或使用 CMD，所以我想知道是否有一种方法可以将我的基于文本的游戏变成一个窗口，例如使用 JFrame 之类的。我所需要的只是一个显示文本的窗口，以及底部的一个栏，让用户输入他们想要的内容（有点像 CMD）。我还不知道该怎么做，因为我在编码方面很新，有人可以帮助我吗？它可能就像一个简单的控制台，因为我目前不寻找复杂的 GUI 或任何东西。

If you try to do it with this examplethen you will need to do this in your game class

如果您尝试使用此示例执行此操作，则您需要在游戏类中执行此操作

private ChanDown frame;

public static void main(String[] args) {
    frame = new ChanDown();
    frame.setVisible(true);
    title();
    game();
}

and change all your System.out.println("text here");to frame.textArea.append("\n" + text here);

并将您的所有更改System.out.println("text here");为frame.textArea.append("\n" + text here);

remove your Scanner, and just take all the input from this code:

删除您的扫描仪，然后从此代码中获取所有输入：

textField.addKeyListener(new KeyAdapter() {
        @Override
        public void keyPressed(KeyEvent e) {
            if (e.getKeyCode() == 10) { //this is key code for pressing enter
                // do the code you want to do when you get the text entered
            }
        }
    });

but it is obvious that you will need to do a lot of adjustments in order to get all that working as intended...

但很明显，您需要进行大量调整才能按预期进行所有工作......

You can write the following in a Batch file

您可以在批处理文件中编写以下内容

@echo off
java -jar TextBasedRPG.jar

and tell your friends to run the .bat file.

并告诉您的朋友运行 .bat 文件。

Yes, it could be run by double-clicking the JAR if it kicked up a JFrame.

是的，如果它启动了 JFrame，则可以通过双击 JAR 来运行它。

Have a look at https://github.com/mafagafogigante/dungeon, a project of mine that uses a JFrame as a terminal-like window (also a text-based game). You can download a compiled JAR file from the releases tab.

看看https://github.com/mafagafogigante/dungeon，这是我的一个项目，它使用 JFrame 作为类似终端的窗口（也是一个基于文本的游戏）。您可以从发布选项卡下载已编译的 JAR 文件。
